Description: This function projects lines and/or points onto selected surfaces.
Usage:
1. DSI prompts:
> SELECT SURFACE
2. Once the desired surfaces are selected, click on DONE. DSI prompts the user to create/choose a coordinate system.
> DEFINE PROJECTION VECTOR
> PICK NODE/PT FOR ORIGIN
3. After accepting the coordinate system, DSI prompts:
> SELECT ENTITY FOR PROJECTION:
4. Based on the selected entity, lines/points are projected onto the surface. If the point or points on the line do not intersect the surface along the global Z or W vector, DSI displays a message:
> NO PROJECTION FOUND FOR XXXX POINT.
